99 Tahoe Headlights.

The headlights on my Tahoe don't work when dimmed. Brights and running lights work just not the dims. Anyone know what the problem could be?

could be a problem with the low beam side of the dimmer switch or drl relay

Ok, The dimmer switch seems to be a common problem. Ill have to check that out. I really hope I don't have to buy a new one though. Those cost some big bucks.

Is your '99 an old body style (OBS) or new body style (NBS)? If OBS and it has the low beam lamps acting as DRL's, as Jeremy-WI stated it could also be the DRL relay as the low beam signal goes thru this relay with the headlights on.

Check to make sure your E-brake pedal is not partialy depressed. I drive a 99 tahoe and my low beams are always on except when the e-brake is on.
